Apply one coat of Glidden Ultra-Hide Gripper. Let that dry.
Apply one (perhaps 2) coats of Glidden Evermore Satin or Ultra-Hide Eggshell finish - your choice of color.
All of these are available at Home Depot.
I will add that - even though these are latex paints and don't smell too bad - seeing as you are pregnant - you might want to have someone do this for you. Pregnant people often are sensitive to paint odors.
